摘要

我国的盐岩层具有盐层薄、夹层多等特点，相对于大型能源地下储备库而言，层状盐岩围岩可视为交互层状介质，其工程力学特性研究是储备库稳定性评价的基础。因此，制备层状岩体模型材料并开展层状盐岩物理模拟试验是非常必要的。为此研发了一种厚度比及各岩层力学特性可调的交互层状岩体模型材料制备方法：首先设计一种薄层切割装置，对预制好的两种力学特性迥异的均质模型材料块体进行切片，再利用一种模型材料软薄层吸附平移装置将得到的两类薄层交互叠加，经过修葺、预压和养护，获得交互层状模型材料块体，最后钻孔取样获取具有不同倾角和厚度比的交互层状岩体模型材料试样。初步试验研究了厚度比、倾角等对交互层状岩体力学特性的影响，结果表明，通过该方法获得的模型材料可以较好的模拟层状岩体特性，为系统开展层状盐岩体物理模拟试验打下良好基础。

Abstract

For the size of large underground energy storage caverns in bedded salt rocks

the surrounding rock composed with many thin salt layers and interlayers can be regarded as an alternate layered medium; and its engineering mechanical properties are the basis of stability evaluation of the energy storage caverns. Therefore

it is very necessary to develop a model material preparation method for physical simulation of the layered salt rocks. A preparation method of model materials and test samples

whose thickness ratio and mechanical properties of the two layers can be adjusted

is presented. The preparation process is as follows. First

two model material blocks are cut into slices respectively by a slice cutter. And then

by using a suction lifter

the two kinds of soft slices are moved and stacked together alternately. Finally

the test layered samples with different dip angles and thickness ratios are obtained by drilling the composed model materials. A preliminary experiment has been carried out to study the influence of thickness ratio and dip angles to the alternate model rock mass. The results show that the samples can simulate well the behaviors of layered rock mass in the physical simulation tests of layered salt rocks.
